WATERING QUESTION: Why are the pots still heavy? I use Plagron lightmix

Hello ! What I doo to water them is this one : For 11L. pot it is about 1L2 to 1L5 per plant (not at the begining, i start with 300 ml then increase slowly), every 3 days about, 4 days. They drink more betwreen veg stage and flowering and early flowering. They drink less at the end. You need to let your soil dry, the surface has to be dry. I scratch the surface of the soil after 2-3 days, then you should have the surface really dry. Put a finger in your soil and you have to feel where you have humidity, the first 2-3 cm should be dry. So what I do and what work for me is : You water correctly and you wait. When I water, I do it slowly, 0.5 ml by 0.5ml. And I wait a bit between plants. You should hear the sound of water (like little bubbles). Wait 3-4 minutes between your 0.5ml watering minimum.

ph in pot is wrong, plant don't drink or is too small for initial watering gnats are very bad too. usually related to bad watering regime ... sort it !
